[0050] Embodiment 1

[0051] As Figure 1 shown, an embodiment of the present disclosure discloses a hatch lifting device 100. The hatch 200 can be installed on the hatch lifting device 100, and the hatch lifting device 100 can be installed on a hoist. Through the operation of the hoist, the lifting and lowering of the hatch 200 can be realized.

[0052] However, the existing hatch lifting device 100 cannot adjust the posture of the hatch 200, which is not convenient for the precise installation of the hatch 200. In addition, due to the different bending degrees or sizes of hatches 200 of different models, each set of hatch lifting devices 100 can only match hatches 200 of a single shape. The versatility and adaptability of the hatch lifting device 100 are relatively poor, and different models of hatch lifting devices 100 need to be purchased to match the corresponding hatches 200, resulting in high installation costs for installing hatches 200 of different shapes.

[0053] To solve the above technical problems, as Figure 1 and Figure 2 shown, the hatch hoisting device 100 includes an installation main body 10, a first connection assembly 20, and a second connection assembly 30. The first connection assembly 20 includes a first connector 21 and a first mounting member 22 provided thereon. The first connector 21 is directly or indirectly connected to the installation main body 10, and the first connector 21 can be connected to the outer surface of the hatch 200. The second connection assembly 30 includes a second connector 31 and a second mounting member 32 provided thereon. The second connector 31 is directly or indirectly connected to the installation main body 10, and the second connector 31 and the first connector 21 are arranged at intervals in a first direction. The first connector 21 can be connected to the outer surface of the hatch 200. Among them, the dimension of the second connector 31 in a second direction is adjustable. The first direction is different from the second direction. By adjusting the dimension of the second connector 31 in the second direction, the attitude adjustment of the hatch 200 on the hatch hoisting device 100 can be realized, which is convenient for the precise installation of the hatch 200 and improves the installation efficiency and accuracy of the hatch 200. In addition, by adjusting the dimension of the second connector 31 in the second direction, the hatch hoisting device 100 can be adapted to hatches 200 with different shapes, improving the adaptability of the hatch hoisting device 100 to hatches 200 with different shapes. The hatch hoisting device 100 has good versatility and adaptability, and the installation cost required for installing different-shaped hatches 200 is low.

[0054] In an optional embodiment, it is also possible that only the dimension of the first connector 21 in the second direction is adjustable, and the above effects can also be achieved.

[0055] In an optional embodiment, it is also possible that while the dimension of the first connector 21 in the second direction is adjustable, the dimension of the second connector 31 in the second direction is also adjustable, and the above effects can also be achieved. Moreover, the hatch hoisting device 100 in this optional embodiment can realize the diversity of different attitude switching of the hatch 200 and can also make the hatch hoisting device 100 match more hatches 200 with different shapes.

[0056] In an optional embodiment, as Figure 1 and Figure 2 shown, the second connector 31 includes an adjustment mechanism 311 and a connection mechanism 312. The installation main body 10, the adjustment mechanism 311, the connection mechanism 312, and the second mounting member 32 are connected in sequence.

One end of the connecting rope 3112 is fixedly connected to the winding part 31112, and the winding part 31112 can wind the connecting rope 3112. By winding and unwinding the connecting rope 3112, the rapid adjustment of the dimension of the second connecting piece 31 in the second direction can be realized. The structure is simple and convenient for manufacturing.

[0058] Exemplarily, as Figure 1 and Figure 2 shown, the winding mechanism 3111 can be a rotating motor. Among them, the winding main body 31111 can be the rotating motor body, and the winding part 31112 can be the output shaft of the rotating motor.

The connecting wire body 3122 is provided with at least two, and at least two connecting wire bodies 3122 are arranged at intervals in the third direction. The first direction, the second direction, and the third direction are perpendicular to each other pairwise. By providing at least two connecting wire bodies 3122, the stable connection between the second connecting component 30 and the hatch door 200 can be realized, and the rotation of the hatch door 200 during hoisting can also be avoided, effectively improving the installation efficiency and installation accuracy of the hatch door 200.

[0061] In an alternative embodiment, as Figure 1 shown, the first connecting component 20 includes a first mounting bracket 23. The mounting main body 10, the first mounting bracket 23, and the first connecting piece 21 are connected in sequence. The first connecting piece 21 is provided with at least two, and at least two first connecting pieces 21 are arranged at intervals in the third direction. By providing at least two first connecting pieces 21, the stable connection between the first connecting component 20 and the hatch door 200 can be realized, and the rotation of the hatch door 200 during hoisting can also be avoided, effectively improving the installation efficiency and installation accuracy of the hatch door 200.
